In Series 3, DCI Tennison has been transferred to a new station and a new assignment: getting prostitutes off the streets of Soho. But when a 17-year-old rent boy is burned to death, her superiors aren't keen on her investigating the murder. The victim was a regular at a center for homeless kids run by Edward Parker-Jones, the darling of the department. As if matters aren't thorny enough, a former lover comes to town and causes Tennison to question her life. Guest stars include David Thewlis (Harry Potter), Peter Capaldi (In the Loop), Mark Strong (Sherlock Holmes), Ciaran Hinds (Persuasion), James Frain (The Tudors), and Jonny Lee Miller (Trainspotting).
